- the fiber is continuously stacked on the outer circumferential surface 2 f ( FIG. 4 B ) of the fiber-stacking depression 30 , thereby producing a continuous core C.
- the carrier web W dispensed from the guide roll 8 is laid over the stacked continuous core C. Then, the continuous core C and the carrier web W are rolled out of the fiber-stacking drum 2 as an integral material. Then, as well known in the art, it may be severed into absorbent cores of individual worn articles on the downstream side (not shown). Instead of producing the continuous core C, individual absorbent cores may be produced by fiber-stacking on the fiber-stacking drum 2 .
